You don't have to select one compiler. We've got many production compilers installed (Intel, PGI, Cray, numerous versions of GCC), a number of official `friendly' versions maintained, and dozens of unofficial builds (e.g. clang).
Given the fast flux of the LLVM interfaces, getting hung-up on the lowest common denominator for a C++ compiler seems weird to me.
